Image dragging and dropping in Silverlight

leave a comment »

In this sample code I am going to demonstrate how we can drag and drop an image from windows explorer to a Silverlight page.

To run the test we should have a page with an Image control. Lets call our Image control as ImgShow. In the xaml, set the AllowDrop property to true. Also add a drop event to the Image control. Once the drop event is added go to the code behind and add the below code to the event.

private void ImgShow_Drop(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.FileDrop))
    {
        FileInfo[] fi = (FileInfo[])e.Data.GetData(DataFormats.FileDrop);
        BitmapImage img = new BitmapImage();
        using (Stream fileStream = fi[0].OpenRead())
        {
            img.SetSource(fileStream);
        }
        ImgShow.Source = img;
    }
}

We are done with the application. Run the application and drag and drop a file from Windows explorer to ImgShow image control.
